laserdiffractionilla

Laserdiffractionilla is a term used in speculative optics to describe a hypothetical hybrid measurement technique that combines laser diffraction with interferometric phase retrieval to characterize micro- and nano-scale structures.

In concept, a coherent laser beam is directed at a sample to produce a diffraction pattern. A reference beam and a beam-splitter setup form an interferometer that encodes phase information into the detected intensity. By applying phase retrieval and inverse scattering algorithms, one can infer particle size distributions, shapes, lattice spacings, and refractive-index contrasts from the observed patterns.

An experimental arrangement would typically include a stable laser source, a beam-splitter, a sample stage, a reference arm with precise path length control, and a high-resolution detector. Data processing relies on Fourier analysis, holographic reconstruction, and model-based fitting.

Potential applications include non-contact sizing of colloids, metrology of microstructured surfaces, and rapid screening of nanomaterials. The technique is proposed to combine the speed of diffraction measurements with the phase information of interferometry, potentially improving accuracy for complex geometries.

As of now, laserdiffractionilla is not an established method in peer-reviewed literature. It is discussed primarily as a theoretical concept or in speculative and educational contexts. Related real techniques include laser diffraction particle sizing, digital holography, optical coherence tomography, and interferometric surface profilometry.
